Certified Supplier Guidebook Chapter 7: Metering Services Introduction

This chapter describes Duke Energy Ohio’s metering obligations for a certified supplier, meter installation procedures, and associated metering charges. These topics are included:

Meter Ownership and Maintenance

Duke Energy Ohio owns, furnishes, installs, programs, calibrates, tests and maintains all meters and all associated equipment used for retail billing and settlement purposes in the Duke Energy Ohio service area.

Meter Reading

Regularly Scheduled Meter Reads:

Duke Energy Ohio reads all meters in its service territory in accordance with the regularly scheduled meter reading dates and whenever Duke Energy Ohio deems a read necessary. End-use customers must provide access to the meters for Duke Energy Ohio to obtain meter readings.   For a schedule of Duke Energy Ohio's meter reading dates, see Appendix D: Meter Reading Schedule of this guidebook. The meter reading schedule is updated in December of each year. 

Estimated Reads:

Duke Energy Ohio will continue to estimate the usage if metered data is lost due to failure of or damage to the metering equipment. Reads may also be estimated in the case of inclement weather, inaccessibility, etc.

Special Meter Reads:

Duke Energy Ohio will provide special meter reads as requested by certified suppliers. Duke Energy Ohio reads meters on regularly scheduled meter reading dates.  A request to read the meter at a different time than the normal meter reading date constitutes a special read. The charges for these meter reads are specified in Appendix A: Certified Supplier Tariff of this guidebook.

Each certified supplier has a secured identification number and password to access a special meter reading request form located on Duke Energy Ohio's Customer Choice Web site.  A certified supplier may also contact Duke Energy Ohio’s Certified Supplier Business Center by email: csbcreps@duke-energy.com, by phone at 513-287-2322, or by fax at 513-287-2718.

Note:  Special meter reads will not be used to create an off-cycle bill or to switch an end-use customer.

Meter Testing:

Duke Energy Ohio will provide meter testing as requested by certified suppliers. A meter test order form is located in the secured section of Duke Energy Ohio's Customer Choice Web site. The certified supplier may contact Duke Energy Ohio’s Certified Supplier Business Center by email to csbcreps@duke-energy.com, phone 513-287-2322 or by fax 513-287-2718. The charges for meter testing are specified in Appendix A: Certified Supplier Tariff of this guidebook.

Metering Requirements

Interval meters are required for end-use customers who choose a certified supplier and have a maximum peak demand greater than or equal to 200 kW for the most recent 12-month period.  Interval meters are also required for those end-use customers that have an interruptible load contract with their certified supplier.

End-use customers who are required to have an interval meter to participate in the Duke Energy Ohio Customer Choice Program may begin service prior to having an interval meter installed, assuming the end-use customer has executed an interval meter request work order approving the interval meter installation. After the interval meter request work order has been executed and submitted and prior to the meter's installation, Duke Energy Ohio will use a company load profile and consumption meter reads for settlement. Duke Energy Ohio will also use consumption meter reads for billing. 

End-use customers are responsible for the incremental costs of the interval meters and the incremental costs associated with the installation of required interval metering.

Duke Energy Ohio may require interval metering for other end-use customers based on a review of the end-use customer’s rate schedule, billing history and class load profile information. If installed, the interval meter will be used for end-use customer billing and settlement purposes.

The most expedient method to successfully enroll an end-use customer that requires an interval meter is for the certified supplier, on behalf of the end-use customer, to send an electronic pdf to csbcreps@duke-energy.com or to fax to (513-287-2718) the end-use customer-signed work order to the Duke Energ Ohio Certified Supplier Business Center.  The enrollment may be delayed if interaction is necessary for Duke Energy Ohio to coordinate obtaining the signed work order directly from the end-use customer.

Requests for Interval Metering

A Duke Energy Ohio Interval Meter Request Work Order can be obtained in the following ways:

Certified Suppliers

End-Use Customers

PLEASE NOTE:  A certified supplier, on behalf of the end-use customer, or an end-use customer, may request that an interval meter be installed where one is not mandated (below the interval meter threshold). The requested interval meter will be used for end-use customer billing and settlement purposes. The end-use customer is responsible for the incremental costs of the meter and the incremental costs associated with the installation of the meter.

Interval Meter Charges and Installation Schedule Charges:

The end-use customer will be billed for the incremental costs of upgrading the present meter and the incremental costs associated with the installation of required or requested interval metering. The charge for an interval meter is a tariffed rate and may be paid as a lump sum or in 24 monthly installments. The ownership of the interval meter will remain with Duke Energy Ohio. The charges for these services are specified in the Retail Electric Service Tariff; Rate MSC-Meter Service Charges.

Installation Schedule:

Duke Energy Ohio’s meter installation schedule is based on the existing capacity to install meters along with other metering work, such as meter maintenance and testing. Interval metering installation requests will normally be processed according to the date received. Meter workload is prioritized to address safety, new meter sets, maintenance, and operational efficiency.

Pulse Equipment

Duke Energy Ohio has meters with pulse outputs available to the end-use customer.  The pulses provide real-time information about the various metered quantities.  End-use customers can use the meter output pulses as an input to load monitoring and load control equipment.  The output pulses are dry contact and are dependent on the meter type.  The available outputs and associated input requirements are as follows:

  • kWh pulse - 3 wire form C contact, mercury wetted, rated at 500 VDC or 350 VAC, 2 amps break, 5 amps carry.  The maximum rating of the contacts is 100 VA. Factory fused at 1/2 amp.  Available on 15-minute interval and non-interval demand meters.
  • kvarh (lagging) pulse - 3 wire form C contact, mercury wetted, rated at 500 VDC or 350 VAC, 2 amps break, 5 amps carry.  The maximum rating of the contacts is 100 VA. Factory fused at 1/2 amp. Available on 15-minute interval meters.
  • 15 minute time pulse - 2 wire form A contact, mercury wetted, rated at 500 VDC or 350 VAC, 2 amps break, 5 amps carry.  The maximum rating of the contacts is 100 VA. Factory fused at 1/2 amp.  Available on 15-minute interval and non-interval demand meters.
  • Rate change pulse - 2 wire form A contact, mercury wetted, rated at 500 VDC or 350 VAC, 2 amps break, 5 amps carry.  The maximum rating of the contacts is 100 VA. Factory fused at 1/2 amp.  Available on 15-minute TOU meters.

All contacts have a 12 to 14 milliohm contact resistance with a 50 milliohm maximum contact resistance.  The contacts typically operate and release in 1 to 2 milliseconds.

All customer-owned equipment connected to Duke Energy Ohio equipment is required to meet the above specifications outlined in each option.

All installations must meet the approval of the local inspection bureau.

The charges are outlined in the Retail Electric Service Tariff; Rate MSC - Meter Service Charges.
